Most people don't move to a country like Bulgaria just for a job. It's fine when you're 2X years old, can work remotely and have time to get into the culture, language, &c. As soon as you have a serious gf/bf or a family you can forget it. One of my colleague is Bulgarian, he moved to Germany because of corruption, lack of quality school, lack of good paying jobs, and that was in Sofia, not some random small town.

There is a reason why it's cheap and everyone is leaving. Also, people underestimate the personal cost of moving to completely culturally different country, you'll never feel at home there unless you live in some kind of gated community or expat district.
